Abstract

A surge-gap device ( ) includes two electrodes ( ), having an inside portion and an outside portion, and an insulator material ( ), which secures the two electrodes ( ). The insulator material ( ) has an opening through the material to expose an open-air gap ( ) that is defined by the space between the two inside portions of the electrodes ( ). In cases of a voltage surge, the surge-gap device permits an arc to pass between the proximate inside portions of the electrodes ( ) across the open-air gap ( ), which gives a current surge a low impedance path to ground. Also included is a fastener ( ) for electrically coupling the surge-gap device ( ) to a ground plane ( ) of an external electrical device ( ) for suppressing the voltage and current surges.
